Logic 4: Muting function logic for machines with openings
Overview
(Logic 4)
The logic described is for using safety devices with dual channel solid state outputs, such as
safety light curtains (Ex. SG2, SG4, SG BODY and SE series), and for devices with output muting
signals that enable muting functions that temporarily suspend safety functions of safety devices
for safety protective measures of robots, conveyor lines, and other machines. This logic enables
the connection of 2 dual channel solid state output (PNP) devices, 2 muting signal output (PNP)
devices (Ex. S3Z, S8, S60, S300 Muting sensor series, limit switch), and 2 dual channel direct
opening inputs.
When all of the safety inputs (X0, X1, X4, X5, and X10 to X13) are receiving safety input signals
(24V DC is applied from the solid state output devices, and the all contacts of connected devices
are closed), the safety outputs are turned ON upon input of the start input.
If any of the safety input signals are cut OFF while the safety outputs are ON, the safety outputs
are turned OFF after the preset OFF-delay time. However, if a muting signal has been applied to
X2 and X3 (X6 and X7), the safety output does not turn OFF even if the safety inputs signal to X0
and X1 (X4 and X5) are cut OFF.
